Thanks to TFW2005 Board member Riverlos for letting us know that he found the Walmart deluxe figures Big Daddy, Grindcore, Jolt, Divebomb at the Walmart in Fontana, CA. He was kind enough to provide these camera phone pics:

I've been waiting for a Big Daddy sighting, now that he's out, it's just a matter of waiting for him to show up here. I would get Jolt too but I cant really afford it. And I like Grindcore's name but not the figure.

Damn Cataclizm1 you always beat me home to report sightings. I too found these only in riverside. Question did your endcap have regular deluxes mixed in too? just wondering if they ship that way.
Also the quality on these was piss poor. The worse I have gotten in a long time. The plastic feels of a lesser quality. I have chips and frayed edges where the spurs were attached. The pin in big daddy's arm was crooked causing stress marks. Horrible paint apps. Jolt has purple spilled all over his visor. Dive bomb's camo paint is so thin you can see brush strokes and the color of the plastic beneath . The silver highlights on big daddy and jolt is so thin its rubbed off in several places. Just all around sloppy. These guys feel alot like the all yellow build team repaint wal-mart years ago. Its like they cut every corner possible
